Abstract: 351,711. Electric signalling systems. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and BLANDFORD, A. R., Siemens Works, Stafford. June 2, 1930, No. 16988. [Class 40 (i).] In remote control apparatus for two or more transformers connected in parallel, each transformer is provided with a phase-shifter A having a fixed three-phase winding 1 connected to a supply M and a movable winding 2 connected to the spindle of the tap-changing mechanism. A relay C connected between each pair of transformers, has two windings 7, 8 connected respectively to the movable windings of the phase-shifters. If the tap-changers of the transformers are on the same tapping point the currents in the two windings of the relay will be in phase and the relay will not operate. If the tap-changer of A is moved forward, out-of-phase currents will flow and the relay will operate and close the circuit of a motor which will move the tap-changer of A<1> forward until balance is obtained. If the tap-changing mechanism of A<1> fails to respond a time delay device will operate and cause the tap-changer of A to move backwards to restore balance. A similar set of operations occur when the tap-changing mechanism is being moved in the opposite direction. To obtain remote indication of the position of each tap-changer an indicator B is provided having a 3-phase fixed winding 5 connected to the source M and a fixed winding 3 connected to the movable winding 2 of the phase-changer. A movable armature mounted between the windings 3, 5 indicates the phase difference between the currents flowing in them and therefore the angular position of the tap-changer.
